and useful Improvements in Loom Attachments, of which: the following is a specification.

My present, invention pertains to looms, and contemplates the provision of simple, inexpensive and easily applied meansthrough the medium of which a weaver is enabled, with the expenditure of very little effort, to pull back or reverse the mechanism of the loom to the point desired and as occasion demands.

WVith the foregoing. in mind, the invention in all of its details will be fully understood from the following description and claims, when the same are'read in connection with-the drawings, accompanying and forming part of this specification, in which:

Figure 1 is a side elevation'of a loom equipped with my improvement;

' Fig.2 is a rear elevationof the same,

connections together with my but with some parts omitted.

Fig. 3 is adetail side elevation showing the circumferentially grooved gear of the improvement improvement as the same appears when the equipment is actuated to. hold said gear in engagementwith the pulley on the top or crank shaft of the loom.

The loom isprovided on the top or crank shaft 1 withia pulley 2 "fixed to said shaft the loom in the direction of .the arrow shown the right of Fig. 6.

in Fig. 1. At 3 is a gear or pinion provided on the motor shaft 4 of the loom, and at 5 is a gear, intermeshed with the gear 3. This gear 5 may be made of various diameters to bring about the reversing of the loom mechanism at a high or low rate of speed, as desired. The gear 5 is carried by a shaft 6,

and on the shaft 6 is also arranged a pinion 7, which may be varied in diameter according to the speed of operation desired. Intermeshed with thepinion 7 is a gear 8 which constitutes an important element of my improvement. The said gear 8, I designate a circumferentially grooved gear, inasmuch as it is provided with an oflset portion 9 in which is a circumferential groove 10, adapted to receive and be engaged by the perimeter of the pulley 2.

The portion 90f the gear 8 may be shaped 'as shown in Fig. 2 or as shown in Fig. 5

without affecting my invention.

Mounted on the shaft 6 and fixedly attached to the loom frame 11 is the bracket 12 for the support of my novel equipment. The said bracket is provided with an upstanding arm 13.

Shaped into a hook 13 at its lower end,

Fig. 7 in order to engage and be supported by the shaft 6, is a vertically swinging lever 15, provided at an intermediate point of its length with a trunnion 16 upon which the gear 8 is mounted and adapted to freely turn. The upper arm of the said lever 15 is preferably, though not necessarily, provided with a series of lateral studs 17 for adjustment purposes.

J ournaled in the arm 13 of the bracket 12is a horizontal rock-shaft 18, to the opposite end portions of which upstanding arms 19 and 20 are fixed as shown in Figs. 2 and 6. The arm 19 is connected througha link 21 with the upper arm of the lever 15, and the arm 20 is connected to ahandle rod 22, which is preferably arranged as shown relatively to the loomv in a bracket 22* on the frame thereof and is equipped at its free end with a hand grasp 23. At its end remote from arm 13, the shaft 18 is disposed in a socket bearing 13, fixed to the inner side of one side portion of the frame 11 as shown at My invention also contemplates theuse of a bracket 24 Figs. 1 to 4 in addition to the bracket 12 and the socket bearing'13 justreferred to, said bracket24: assisting in the support of the rock-shaft 18, and the said 5 brackets and socket bearing being the only elements that it is necessary to attach to the loom to hold my'no'vel equipment in proper working position. The bracket 24.- is fixed vto one side of the bracket 12 and extends downwardly therefrom, and is fixed at its lower end to a portion of the loom frame as clearly shown in Figgl} i Heretofore, when a loom stopped it has been necessary for the weaver to 'pull the loom mechanism back by hand,'and this has been found to be a'laborious operation.

The pulley Qis fast on the crank shaft 1 of the loom and is only in motion whenthe loom is running. The gears.3, 5, I7 and 8 2 and the'pulley 9 are constantly in motion, due to'the fact'thatthe gear 3 is fast on the -motor shaft 4 which" runs the loom. When the loom is" running the attachment is posi- "tioned 'asshown in Fig. 1, the portion 9 of gear being then out of contact with the pulley 2. To pull back or reverse the mechanism of the loom, the weaver pulls on the handle 23' and thereby drawsthe gear portionor pulley 9 intoengagement with .the pulley '2 as shown in-Fig, 3. Then when the loom comes to the stopping" point, a tappet 1 adjustablyfixed on the"shaft 1 "strikes the lever '15 and thereby moves the pulley 9 away from the pulley 2 and causes the loom to stop. The tapp'et l is a'djustably fixed on the shaft 1,'as stated, in order that it may be positionedto' stop the loom -where wa'ntedf It will be readily appreciated froin the v foregoing that my novel attachment is sim- "ple'and inexpensive in construction and is susceptible of being expeditiously and'e'asily applied to' a loom, without entailing the employme nt of highlyskilled labor; and it will also be appreciatedthat through the inedium of the novel equipment the reversal or pulling'back of'the loom mechanism may be accomplished with the expenditure of extremely little effort on" the part of the 'W eaVe r. 1 I'have entered into a detailed description of theconstruction and relative arrangement ofthe 'parts embraced in the present "and-preferred embodiment of my invention,

understanding of" the said embodiment. I do not desire, "however, to be understood as confining myself'to the said specificpon- "struction and relative arrangementbf parts,

since in the future practice of'the invention j ."varlous changes -1n the form and relative Tarrangement'o'f the elements may be made,

without involving departure from the scope of my invention as defined in my appended ss'elaims.
